From 8c483758afe4f1dc34cb8319f36302aa31776ac9 Mon Sep 17 00:00:00 2001 From: Robert Abel Date: Sat, 10 Feb 2018 00:50:11 +0100 Subject: auxdisplay: charlcd: use null character instead of zero literal to terminate strings Using '\0' instead of plain 0 makes the intent clearer that this is indeed a string and not a series of integers.
